Next month I'm having the side stairs in my 1891 house restrung. It will involve removing the plaster from underneath, but only up to the cove molding that runs along the wall. Afterwards I have the choice of restoring the plaster, or sticking up sheetrock. My plaster men are quite capable of doing the plaster. But it will cost me more. I like to keep things as original as possible, so I'm leaning to plaster. But it would be encouraging to me if I knew that there was some advantage of using plaster over sheetrock.
